[SOLVED] Zimbra and Skype

1. The Skype network consists of "super node" clients, these are regular clients that independantly make the decision to become "super nodes" and start proxying other users traffic through their local network.

2. The Skype application is know to covertly install an application that retieves information from the host machine and sends this on to Skype HQ servers without consent or the knowledge of the users.

"...A very interesting moment about the Skype network is that it 'self-modifiable'. If you have the application installed, your computer may turn into a Super Node, without you even knowing it, because those capabilities don't have a noticeable impact on a computer's performance. SNs basically store the addresses of up to several hundred Skype users, without carrying any voice, text or file-transfer data. In that manner, the more Skype users come online, the more super nodes become available to expand the capacity of the network...."

Thanks Raj,

The important bit for me is:Conclusion: There are several factors responsible for the success of Skype. First of all, the voice quality is better compared to other applications. It works without a problem on computers with firewall. It is very easy to install and use. Skype's security is also a big advantage. Everything that is being transferred across the network is being encrypted to ensure privacy. As a result of that, even if hackers intercept the data being transferred, they won't be able to decode it.

The Skype application does not include any adware or spyware. But, there are cases when third parties have managed to add such functionalities (not only for Skype), so itís really important that you download it from the right place.
